I test it in
libvirt-0.8.2-23.el5 & libvirt-0.8.2-24.el5
kvm-83-243.el5
kernel-2.6.18-294.el5
Gnome & KDE

the steps is as same as zhpeng.

when start guest , the SDL fullscreen pop up but have nothing except black and at the same time , the host hung.Only repower can end this situation.
I test it on both Gnome and KDE.
